Specification of Letters Patent.

Patented Dec. 9, 1919.

Application filed March 11, 1918. Serial No. 221,662.

To all whom it may concern:

oeit known that l, FR-iNK F. Snrrrrr, a citizen of the United Stat s,and a resident of the city of Newark, in the county. of Essex, State ofNew Jersey, have invented certain new and useful Improvements inDoor-Lock Mechanism, of which the following is a specification.

The improvements relate to locking devices of the emergency exit orionic lock variety and have for their objects, among others, theprovision of simple a1 d effective means for automatically dogging orblocking the belt which engages the socket-plate, and holds the bar, andany other bolts if other bolts are connectedtherewithin un lockedposition while the door is open. This provision is very desirable wherethere a flush sill or a 'carpeted floor, as by holding the bolts inretracted position when the door is swinging injury to the sill, flooror floor covering is avoided, as well as injury to the bolts themselves.

The improvements are illustrated in the accompanying drawings, in whichFigure 1 is an elevation of an automatic dogging device with theadjacent socket plate in vertical section; Fig. 2 is an inside edge viewof the some removed from the face of the door; Fig. 8 is a view from theedge or side opposite that of Fig. 2;. Fig. is a vertical section of thehousing substantially on the line 4-4- of Fig. 2, with the partscontained in said housing shown in elevation, and in a differentposition from that of Figs. 1 and 2; Fig. 5 is a detail of the bolt inside elevation; Fig. 6 is an edge view of the bolt detached; Fig. 7 is adetail of the tripping lever for releasing the dogging device with thepins for which it is mounted in the housing and connected with theadjacent cooperating member.

The rod A, in the illustration of the invention shown in the drawings,is mounted to move up and down, and to retract the bolt or boltsconnected therewith on its upward movement. The downward and-lockingmovement being caused wholly. or partly by the gravity of the said rod.This general construction is shown and described in my Patent No.1,117,457, of November 17 191%. The rod may be moved upwardly by meansof a panic bar, such as that shown in, the said patent or any othersuitable means' A sleeve C receives the threaded upper end of therod Aand connects it with the rod in, to which the said sleeve is joined, therod E extending upwardly therefrom into the housing H and connectingwith the bolt B.

The upper end of the rod E is connected with the bolt B by means of thelink consisting of the medial part L, the lower forks F spanning thereduced part E of the rod, and the upper forks G similarly arrangedwithrespect to the lower end of the bolt. The forks F are pivotallyconnected with the upper end of the rod at E and witi the tail B of thebolt at J, the pivot 5 be ing out of alinement vertically and insice thepivot K of the bolt, so that the upward tirust of the rod communicatedto the tail of the bolt through the link will cause the said bolt torock on its pivot and withdraw its nose from the socket M. Movement ofthe rod in the opposite direction, will, therefore, cause the bolt tolook. In this .inanner a ver sim le stron and ,ositivo connectionbetween the vertically operating rod and the bolt is provided. The rod Eextends through an opening H in the bottom of the housing H, and is heldagainst lateral movement in the direction of the door by the pin Nextending through said housing.

If the bolt were not provided with the automatic dogging means it wouldreturn to its locking position as soon as the rod A was released andallowed to fall, and as this usually occurs during the opening movementof the door upper and lower bolts controlled by the rod would projecttherefrom upwardly and downwardly and strike anything in their path, tothe injury of floors, floor coverings, and other parts, if not to thebolts, as hcreinbefore noted. The rocking dog D is therefore providedfor the purpose of detaining the bolt and holding it in its restrictedposition during the opening and closing movement of the door, and thisalso holds the rod A and any other bolts that may be connected therewithin unlocked position. The dog or detent D is pivoted by means of a pivotpin 0 extending therethrough and secured at its ends in the housing, andthe portion of this member nornally below its pivot is made of greaterthickness and weight than the upper part, so that when released it movesby gravity to the position shown in Fig. 4:. When the door is closed,however, it is held out of this position by the lever B pivotallyconnectcd with the dog D at P and pressed inwardly by contact of itsenlarged upper end with the strike plate S depending from the socketplate.

The lever B oscillates on the pivot T by which it is mounted on theoutside of the housing, and the pin P is secured to its lower end,extends through an opening in the housing and through the upper end ofthe dog D. When the door is closed therefore and the upper enlarged endof the lever B is pressed inwardly, the upper end of the dog is movedinthe opposite direction and its lower weighted end raised. The devicesremain in this position while the door is closed. When the door isopened, however, the pressure on the upper end of the lever It isimmediately released, and the weight of the lower end of the dog throwsits upper end into the path of the pointed eX- tremity of the bolt tailB, so that the bolt and the rod connected therewith cannot re turn tolocking position. When the door reaches its closed position, however,the up per end of the lever B is again thrown back by contact with thestrike-plate S and the detent extremity of the dog D d awn out fromunder the tail B so that the bolt is incidentally shot and the doorlocked.

What I claim is:

l. The combination of abolt, a pivot on which said bolt is mountedintermediate its ends, said bolt comprising a locking portion on oneside of the pivot adapted to move into and out of locking position whenthe bolt is oscillated and a tail portion on the other side of thepivot, a rod mounted to reciprocate substantially in alinement with saidlocking portion and normally held by its gravity in bolt lockingposition, and a connecting member between said rod and said tail portionand positively secured to both whereby lengthwise movement of the rodimparts movement to the bolt in substantially the opposite direction,the arrangement being such that when the rod moves toward the pivot thelocking portion of the bolt moves toward the rod and from its lockingposition, and when the rod moves away from the pivot the locking portionof the bolt moves away from the rod and to its locking position.

2. The combination of a bolt, a pivot on which said bolt is mountedintermediateits ends, said bolt comprising a locking portion on one sideof the pivot adapted to move into and out of locking position when thebolt is oscillated, and a tail portion on the other side of the pivot, arod mounted to reciprocate and nor a ally held by its gravity in boltlocking position, and connection between said rod and said tail portionwhereby lengthwise movement of the rod imparts movement to the bolt insubstantially the opposite direction, the said connection between therod and the bolt com"- prising a link pivoted and positively connectedto the rod and to the tail portion of the bolt, and arranged to move onlines angular to the movement of both rod and bolt.
